Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the pipeline structure figure of the tunnel dehydrator body interior of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, invention is described in detail.
As illustrated in fig. 1 and 2, the Electromagnetic Heating tunnel type steel band fluid-bed drier that the present invention proposes, including electromagnetic high-frequency heating part and drying part；nullDrying part includes tunnel dehydrator main body 1、The steel band 2 for transmitting material of dehydrator main body 1 of passing through tunnel、It is arranged in parallel the snorkel group 3 blown in tunnel dehydrator main body 1 sidepiece and past tunnel dehydrator main body 1、It is arranged on multiple gas skirts 4 on the top of tunnel dehydrator main body 1、Connect the many discharges 5 in each gas skirt、Connect the cyclone separator 6 of gas skirt 4 by discharge 5 and be arranged on the air exhauster 7 on cyclone separator 6 top，The side of described steel band 2 is provided with a vertical air inlet pipe 8 of row，Every of snorkel group 3 penetrates the snorkel of tunnel dehydrator main body 1 and is correspondingly connected to every vertical air inlet pipe 8，Every vertical air inlet pipe 8 is connected and installed with the enterprising trachea 10 of the band being separately positioned on steel band about 2 both sides and band lower inlet duct 11，With on enterprising trachea 10 and the pipe shaft with lower inlet duct 11 all distributing installation have blowing nozzle 12，The blowing direction of blowing nozzle 12 is both facing in steel band 2.Steel band 2 is provided with the live-roller 15 driving steel band 2 motion.
Electromagnetic high-frequency heating part includes electromagnetic high-frequency heating air device 13 and is arranged on the high pressure positive blower 14 of electromagnetic high-frequency heating air device 13 air intake, and the outlet air end of electromagnetic high-frequency heating air device 13 is connected to described snorkel group 3.
The quantity of cyclone separator 6 and air exhauster 7 is all multiple, general two gas skirts share a cyclone separator 6 and air exhauster 7, being provided with the air vent of adterminal air exhauster 7 in steel band transmission side and be connected to a backflow trachea 9, this backflow trachea connects the snorkel being arranged on steel band transmission top, direction in snorkel group.
Operation principle: material to be dried enters in tunnel dehydrator main body with steel band after being laid on steel band, the hot-air that electromagnetic high-frequency heated air device is heated by high pressure positive blower is delivered in every vertical air intake duct by every snorkel of snorkel group, two-way is divided from vertical air intake duct hot-air out, one tunnel entrance leukorrhagia air intake duct out blows to steel band from outlet be heated, material on steel band is carried out conduction of heat heating, drying by the steel band of heating, another road enters the material out blowing to steel band from blowing nozzle with enterprising air flue, direction and steel band translational speed are contrary, contact with material while that the gas of blowing nozzle blowout making material move and it is carried out convection stoving, total multiple rows of blowing nozzle in tunnel dehydrator main body, adjacent two row's blowing nozzle dislocation are arranged, the material on steel band is thus made constantly to stir acceleration drying course.Tail gas after drying is collected by gas skirt, and gas skirt is corresponding with the position of blowing nozzle.Be arranged on the gas skirt at forward top, steel band transmission direction tail gas (owing to the moisture of at this moment material is higher, tail gas moisture content is higher, temperature is relatively low and in tail gas dust less) discharged by air exhauster after the dust separation in tail gas by cyclone separator.
Wherein, it is arranged on the tail gas of the gas skirt of the forward end in steel band transmission direction (owing to the moisture of at this moment material is relatively low, tail gas moisture content is relatively low, temperature is higher and in tail gas dust concentration bigger) by cyclone separator, the vertical air intake duct being backed into forward top, steel band transmission direction by air exhauster by the trachea that refluxes after the dust separation in tail gas is recycled, improve the utilization rate of energy, reduce energy consumption, decrease again the discharge of dust.
Above-described embodiment only have expressed the several embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore understands that be the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to making some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
